A method for controlling a precharging circuit. An electric supply unit is coupled to an intermediate circuit having an intermediate circuit capacitance. Through a control unit for connecting the supply unit to the intermediate circuit, an electric current of the supply unit is initially conveyed via a precharging resistor of the precharging circuit and then the precharging resistor is bridged. Prior to a following renewed connection of the supply unit, an overheating criterion for the precharging resistor is checked and, when the overheating criterion is met, the connection is blocked.
